Introduction of leveling ruler:

Usage: used in testing, measuring, lineation, equipment installation, industrial project construction.

Advantages:

1、Leveling ruler, parallel leveling ruler, bridge leveling ruler, angle leveling ruler, cast iron leveling ruler are light in weight. A leveling ruler of 3m only weight 9kg.

2、They are easy to use: a worker can easily move a leveling ruler of 6m long and carry out measuring.

3、Anti-deformation: the yield point of normal steel material is 30kg, that of normal casting is 38kg, and that of our material is 110kg. So, its anti-bending index exceeds that of others by a comfortable margin.

4、They are easy to conserve: they either can be hung or lay on the ground. Their linearity and parallelism will not be influenced if you would not use it for a long time.

5、They are not apt to rust: they need not to be oil if you using it frequently. If you will not use it for a long time, only a thin film of commercial oil is needed. They are used in testing unevenness and nonstraightness when testing a machine tool. The two work faces work with gauge block and level meter and carry out the measurement of parallelism of two guide ways of different height and the levelness of two unlinked guide ways .

It also can be used in testing the verticality of two mechanics, when a angle square can’t carry out the measuring work itself and in equipment installation and testing.

Leveling ruler includes parallel ruler, bridge leveling ruler, angle ruler, cast iron leveling ruler, triquetrum leveling ruler and special leveling ruler which used in testing the accuracy of machine tools guide tracks and work benches, the geometrical accuracy, testing precise accessories, scrap processing, etc. They are the standard for precise testing.
